The present 'invention.-relatesi to new and use,- ful improvements in internal combustionengines of the L-he'ad or overhead valve type, partic-' ularly those used in automobiles, and has for its primary object to provide, in a manner as hereinafter set forth, an engine embodying novel means through the medium of which the valves may be conveniently and adequately lubricated.

Another important object of the invention is mg to provide a lubricating means for the .valves of automobile internal combustion engines which may be controlled from the instrument board of the automobile.

Other objects of the invention are to provide a valve lubricating means of the character described which will be simple in construction, strong, durable, highly eflicient and reliable in operation, and which may be manufactured and installed at low cost.

720 All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection .with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, .and wherein:

Figure 1 is a view in side elevation of. an internal combustion engine, showing a lubricating means in accordance with the present invention thereon.

Figure 2 is a fragmentary View in vertical sec tion through the forward end portion of the engine.

Figure 3 is a horizontal sectional view, taken substantially on the line 3-3 of Figure 2.;

Figure 4 is'a view in'vertical section, taken substantially on the line 44 of Figure 2.

Figure 5 is a detail view in vertical section through one of the valve guides.

Referring now to the'drawings in detail, it will be seen that the reference numeral 1 designates generally an internal combustion engine which includes a block 2 of the usual water-'cocled type. Mounted in the usual mannerin the block 2 are vertical guides 3 in which the intake and exhaust valves 4 are mounted for reciprocation.

At an intermediate point, each guide 3- has formed therein an internal, annular groove or channel 5 communicating with an inletport 6. Thestems of the valves 4 have formed therein circumferential grooves or channels 7 and spiral grooves 8 which communicate with said grooves 7. Of course, the grooves 7 and 8 in the valve stems receive oil from the groove or channel 5 .55- in the guides 3.

. Extending longitudinally through the block 2 is a c'onduitQwhich terminatesin upturned for- Ward and rear end zportions'lo and .11, ,respec-.

tively. As illustrated toadvantage inFigure 3 of the drawings, the conduit 9 extends immediately 60, adjacent the guides 3 and has longitudinally spaced openings or cut-outs therein communicating with the ports 6 and in which said guides are engaged or seated. These openingsor cut-outs in the conduit 9 are designated by the reference numeral 12. It will thus be seen that the conduit 9 communicates with the guidesB.

Mounted on the upturned forward end 10' of the conduit 9 is an oil reservoir 13 beneath which is a control valve 14. The top of the reservoir 13 is provided with a suitable valve 15 which permits air to be injected and stored under pressure in said reservoir 13. r

Mounted in the upturned rear end portion 11 of the conduit 9 is a vent valve-1 6. The valves 14 5; and 16 areactuated simultaneously to open or closed position from the instrument board 17 of the automobile through the medium of a rotary rod 18 having one end connected directly to said valve 14. At an intermediate point, the rod 18 has'formed therein a crank throw 19 with which a'link 20 which actuates'the vent valve 16 is connected. Briefly, the operation of the invention is' as follows: The'lubricating oil is, of course, placed in the reservoirl3 and, if desired,air under pressure may be injected into the said reservoir above the oil. Then, when the valve 14 is opened, the 'oil will flow through the conduit 9, pass into the grooves or channels 5 in the guides 3 through the ports 6 and enter the grooves 7 and-8, thus thoroughly lubricating the valves in said guides. As, will be apparent, opening of-the vent valve 16 will cause the flow of the lubricating oil through V l the conduit 9 to be accelerated and closing of said vent valve will assist in retaining the lubricant in the conduit 9. The invention may be embodied in the head of an engine of the overhead valve type for lubricating the valves in said head.

It is believed that the-many advantages of a- 0' valve lubricating means in'accordancelwith the present invention will be readily understood, and although the preferred embodiment of theinvention is as illustrated and described, it is to be understood that'changes' in thedetails of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

1. In an engine including a. block, guides 11D mounted in said block, valves operable in the guides, a conduit in the block communicating with the guides for discharging oil thereinto, a control valve for the oil in the conduit, a vent valve in the conduit, and common means for actuating the control and the vent valves.

2. In an engine including a block, guides mounted in saidv block, valves operable in the guides, a conduit extending through the block and communicating with the guides for discharging oil'thereinto, means for supplying oil to the conduit at one end of said conduit, a control valve for the oil in said one end of the conduit, a

of the conduit, a vent valve in the other end portion of the conduit, and common means for actuating the control and vent valves.

4. In an engine including a block, valves operable in said block, a conduit for conveyingoil to the valves, means for introducing oil into the conduit at one end thereof, the other end of the conduit communicating with the atmosphere, a control valve in said one end of the conduit, a vent valve in the other end portion of the conduit, and common means for actuating the control and vent valves. 7

5. In an engine including a block and a head, guides mounted in said head, valves operable in the guides, a conduit extending through the head and communicating with the guides for discharging oil thereinto, means for supplying oil to the conduit at one end of said conduit, a control valve for the oil in said one end of the conduit, a vent valve in the other end portion of the conduit, and common means for actuating the control and vent valves.
